Chainsaw Repair

Probably the 2172?

For older how about the 670.

No Jreds in my area either.  Stihl or Husky.  When I say Dolmar it's what's that never heard of it. 
Most popular carb kits for Jred IMO would be Tillotson RK23HS 625-670, Walbro K10-HD 2171-2172, K24-HDA 2157-2159.
Can't remember Zama # for mid size late models 2152, etc.
Shep

Don't know that this helps but I have a Cs2159C & an old (two coils) 670 West Coast.
Red isn't a popular color in my area. 

There are no honest to goodness Jonsereds dealers within 40 miles of my house. You don't normally see them on Craig's list locally. I see plenty of them at the GTG's though.

As far as dealers go, The local Husqvarna dealers may as well just be box store sellers. One is a tool rental place and the others are all city hardware stores. The rental outlet seems to have a 60 day turn around on even the slightest repairs and the repairmen have to work on all kinds of equipment.

There is one true Stihl fix-em dealer who does repairs within 20 miles of my house. They work full time on Stihl POE. Some of the others have a part time (retired) guy that fixes them at his home shop or they send them somewhere else to be repaired or maybe even have a certified repairman but he works mostly on other equipment.

There is timber falling always going on around here but the majority of chainsaw use is firewood. To the West is big grain farms. To the East is mixed agriculture.
